One source tells us ... "We need him on the field and if he gets hurt
during the off-season doing wild stunts ... it would be bad and it ain't
worth it. He is too valuable to the team."

Another source
expressed similar concerns -- "if he gets a busted ear drum or an
infection, it could have serious effects on his off-season training."

Several
of Suh's teammates also told us they were surprised the organization
would allow him to participate in the first place ... since there is a
real serious risk he could hurt himself.

One last source -- who
happens to be an African-American -- added, "He's a big dude ... and
'black' and 'pool' just don't mix. He's built for football ... not belly
flops."

TMZ first reported Tuesday that Suh is part of the cast for the ABC show,"
which reportedly premieres March 19 and also includes Kareem Abdul-Jabbar,
comedian Louie Anderson, former "Baywatch" actress Nicole Eggert and others.
